Honestly not my experience. I can’t just send it off to blindly work on a feature and expect quite the same level of correctness as Claude, but I’m also not trying to use it like that.

If you want to plan out features then use agents to implement them in small chunks, deepseek has been comparable to Sonnet 5.5.

But this is just early stages for me, I was fully using Claude models for a while and decided to switch after getting annoyed buying extra credits for personal projects.. I was like “eh I’ll just throw a few bucks in openrouter and see how it is this time” and it’s been so much cheaper than buying Claude api credits when my subscription is out

It uses tools in my custom harness about as well as Claude models and makes edits to files doing specific things about as well as I’d want.
